my baby is 2.1 year old, and not speaking a word ,but sometimes he responds to his name... Also if he want something then he will pull someones hand and he will take them to that place. but he is very active and shout out loud, playing with the ball, opening and closing the bottle cap. He observes and try to imitate the actions what we do but not speaking any word.. if he is thirsty then he brings the water bottle and give to us... please suggest how to make him to speak..?
